Should you not see the specific answer you’re seeking, please don’t hesitate to contact us!
How does the climate affect my roof?
The Southern Alberta climate (wind, rain and hail) is a big deciding factor when it comes to roofing/re-roofing your home. You can rely upon our roofing experts to educate you about your roof and go over the best roofing options for your specific needs.
What’s the best problem resolution you can provide?
There’s no substitute for experience – we’ve encountered just about every new roof and re-roof situation! We provide effective problem resolution and reliable consulting services, letting customers know which products will work for their roof and why.
When is it best to remove old shingles?
Shingles can last as long as 20 years before needing replaced, as long as you chose high-quality shingles and had them professionally installed. Sometimes it’s possible to re-roof without removing the old shingles. However, this will depend upon many variables including how many layers of roofing you already have, how you want the new roof to appear and even local building codes. Shingles are heavy and every roof is designed to withstand a certain load – better have a roofing expert take a look at it to ensure you don’t have too many heavy layers.
When is it best to replace underlying plywood?
Many older homes were roofed with wood shakes or shingles, while more modern homes often feature laminated panels such as plywood in their roof decking. With proper installation, your underlying plywood can last as long as 70-100 years. Unfortunately, plywood can rot or mould over time (especially when a leak occurs) and it may require replacement before then. You should replace your underlying plywood as soon as you notice leakage has occurred. Various things can cause leakage, including year-round condensation, inadequate attic ventilation, wind damage, ice/snow damming, leaking ducts and vents and even damages caused by falling tree limbs or animals.
How many layers of old roof should be removed? Do you have to remove all of the old shingles?
Most building codes will allow 2-3 layers of organic or fibreglass asphalt shingles. It mostly depends upon the pitch and slant of your roof and whether or not it can support the additional weight of multiple layers of shingles. Sometimes you can re-roof over the existing shingles and sometimes you can’t. Shingles are heavy and every roof is designed to withstand a certain load – better have a roofing expert take a look at it to ensure you don’t have too many heavy layers.
Why and when should you tab shingles?
Many customers want to know the differences between architectural shingles and 3-tab shingles. 3-tab shingles are no longer being manufactured and have been replaced by architectural shingles. Architectural shingles typically last longer and come with a longer warranty. They also come in many sizes and shapes to give your roof a more dimensional look than that of their predecessors.
Can you repair cedar shakes?
We specialize in fibreglass (asphalt) roofing and torch-down systems.
Do you replace old flashings?
We provide roofing repairs and re-roofing services in addition to our new roofing installations.
How do I make an insurance claim?
Once the storm is over, look for any damages to your roof and be sure to take photos to document the extent of your damages. Contact your insurance company and find out what your insurance policy covers – some policies may require a certain amount of damage before you can file a claim. You will also need to get a roofing estimate from an experienced contractor. Most insurance companies will let you select the roofing contractor of your choice, and most roofing contractors are experienced at dealing with the insurance company on your behalf.
How do I know if I have hail/wind/rain damage?
Here are some tell-tale signs of hail/wind/rain damage to watch out for:
Can you work in cold weather?
Yes, we provide our services year-round, including winter!
What happens to my old shingles after a roofing job?
We work hard to maintain a safe worksite and we thoroughly clean up all debris, including scrap roofing materials and nails. All of our garbage is hauled away, so you never have any clean-up worries. You’ll never even know that we were there!
What’s your warranty like?
We carry a five-year labour warranty. That’s your guarantee that we’ll back up our workmanship 100%. We take pride in our work, and we never sub any of it out!
Do you charge to inspect my roof? How much will the job cost and why?
From new construction to re-roofing and roofing repairs, we provide free, no-obligation estimates for any job. The cost of the job will vary depending upon several factors, but you can rest assured we’ll thoroughly discuss all of the costs involved prior to beginning or completing any work!
Why do you still hand-nail roofs?
This ensures the job will be done right! Hand-nailing your roof allows us to ensure the nails are properly placed at the correct depth, so they’re not over- or under-driven in relation to the shingles. This is important because when nails get driven between shingles, it can cause leakages. There’s far less room for error when using a nail gun because we can actually feel when the nail catches!
